What is the best air bag I can use in my NAERC Chaise setup that is reliable and will provide at least 4 inch travel. I have easyride air-bag in it now (Standard NAERC Setup) and one is leaking. Any suggestion is greatly appreciated

I have two bags that I am not using.......they are like new, I just used them for fitment.
They are from Airbagit, I couldn't use the because they rubbed on my Held control arms.
Let me know if your interested
